WARNING
To carry out this operation:
1) Make sure that the gearbox is cool enough to work in safety without scorching the hands. Wear adequate
gloves if necessary.
2) Unscrew its bolts and remove the rear cover of the gearbox.
CAUTION
Watch out: oil will come out.
3) It is advisable to bend the rotary Gyrovator forwards.
4) Slip the two gears from the drive shafts and invert their position.
Alternatively, replace the pair of gears with the spare set.
IMPORTANT
- While changing gears pay attention that the spacers (Fig. 21) fitted behind the gears do not fall in the
gearbox.
- The falling of the spares (Fig. 21) inside the gearbox can cause the braking of the gears.
The name-plate on the cover gives the number of teeth of the gear pair originally installed by the Manufacturer,
furthermore, as on page 7 of this handbook, there are the speeds pertaining to the pairs of gears mounted on
purchase, plus of the spare pairs.
Each machine with gear change has a label which indicates the gear couple mounted as first equipment.
The label is attached to the third-point.
CAUTION
Be very careful and ensure to use the right gears, since some gear pairs cannot be inverted, and gears from
different pairs cannot be interchanged.
Strictly comply with the pairs of gears indicated, in the chart on page 7.
Optimum tilling depends on two factors:
1) Forward speed of the tractor.
2) Rotation speed of the blade-carrying rotor.
The faster the rotor rotates, the more chopped up the soil will be.
CAUTION
Detach the machine from the tractor or turn off the tractor engine and rest the machine on the ground
before subjecting the gearbox to any adjustments or inspections.
